c++.idde - ClassExpress problems porting from MS VC++ ver 6

reply Andrew Corkan <acorkan icubed.com> writes:
    Greetings and a sincere thanks to Mr. Bright and Mr. Knepper for all
their work and support on this great product.  I have ordered the CD, so
maybe the new DM tools will solve my problem, but I thought I would post
this just in case.

    I am currently using Symantec ver 7.5 (7.60b actually) compiler.
Having found DigitalMars now continuing that fine product I decided to
port over some programs from Microsoft VC++ to see if I can justify
using DM for our company.
    The big problem in the port is that when I now invoke ClassExpress
and look at the "Message Maps" it does not list the control define
values in the "Control ID's in Class", but rather a bunch of numbers.
In fact if I try to scroll through list of numbers the IDDE crashes.
The "Data Transfer" looks OK, and I can't see what in the source code
has changed or might be incompatible with the IDDE.
    What is the tool incompatibility when moving from MS VC++ to DM?  Is
there a document describing this problem?

Thanks
Andy

In general, to use resources in DM's IDDE, they need to have been created by
DM's IDDE.

    Isn't there any way to convert, or documentation on the different
standards?  I looked at the Microsoft generated code and some SC++ generated
code and I can't see any difference.  Does anyone even know the difference or
what the IDDE is failing to read or see in the source?  Is there a parallel file
that I need to generate?
    Even if it takes some effort I am willing to try since I would much prefer
to use the DM compiler.
    Thanks.

The trouble is I don't know and don't have the resources to work on the
problem right now. It's been years since I looked at resource formats in
detail. There's definitely a bug in the IDDE, though. The best I can suggest
at the moment is to redo the resources, or use a resource editor to remove
them from the exe and rebind them, etc.

Walter,
    I will post on the other news lists if anyone else has dealt with this
problem.  If you have, or know of, any documentation on ClassExpress please pass
them on to me.  I will do some experimenting when I get a chance, and let you
know what I come up with.  Thanks.

Walter,
    To clarify the problem: I tried porting over three MFC-based MSVC++ (ver 6)
projects.  I had to make some minor changes in the 'stdafx.h' file and they all
compiled and ran just fine.  When I tried to use ClassExpress I found that two
projects could be edited fine, but one failed.  There were no obvious
differences in the projects, except that the one that failed had many more
dialogs that the others.
     My conclusion is that IDDE is generally compatible for resource and class
editing with MS VC++, but sometimes there is a problem and it can't correctly
display the resource ID's and crashes.
   I realize that this is not a priority for you, but if you can pass along any
information on how or what files ClassExpress needs to read, I can look into it
further on my own time.  Even just a list of the files and relationships that
ClassExpress needs to read would be a good start.
    Thanks again for your help.

    I am sure this is not the case based on my experimenting this morning.  I
can edit the ".rc" file and add a new control, with a new IDC_ name, to an
existing dialog box, and that ID name will appear when I open ClassExpress, even
though it has not been defined in "resource.h" or before the program has been
compiled.
    I am pretty certain that ClassExpress loads the .rc file, and also reads a
".cle" file to find out which .h and .cpp files contain the message maps,
etc...  It may also read the "resource.h" file.
    What is so strange is that when ClassExpress fails to load the correct ID's,
it still is correctly loading the message maps and automation variable data.
    At this point I think the problem with ClassExpress is that it is hyper
sensitive to the formatting of some of these files and cannot alert the user to
the problem or gracefully deal with the problem.  When I have more time I can
try to identify the file that is causing these problems, and in the mean time I
will see if anyone else responds to these posts.

    Other than this ClassExpress problem, all three MFC VC++ ver 6 projects were
recompiled and run just fine!

You're probably right.

Glad there's at least one bright spot!

Problem Solved!

The problem was in the .rc file.  For what ever reason the project I brought
over had numbers (ie. 63552,10254,...) in place of menu resource ID's (ie.
IDM_FILE_OPEN,IDM_FILE_SAVE,...) in one of the menus.  After i went through and
replaced them with the correct resource ID defines, from "resource.h",
ClassExpress works fine!

Basically there is a problem parsing raw numbers for the ID's and ClassExpress
was choking on that.

The CD came yesterday and I am off and running.
